"Once you've had a wonderful dog, a life without one, is a life diminished."
True words. I say grieve briefly and get another, but that's me. We're all different. I knew it'd be very rough on my wife after our Dobe died so I got our current dog as his replacement beforehand. She had a dog she loved to help her grieve. Now with the new house we have 3 dogs so it's a non-issue.
This is exactly what I would do to help easy the grieving process. I would also hate not having a dog as a friend in my life.
